Possibility #1 : you and your wife are both deceased, and don't know it.

Possibility #2 : you have an identical twin brother, and don't know it.

Possibility #3 : secret powers have prepared a double to replace you. They were planning to kidnap you today at the store while your wife wasn't near, take you out the side door, stuff you in a van. But they got the clothes wrong. They will try it again soon.
